[Bug c++/28088] [4.1 Regression] Internal compiler error on boost mpl test/apply.cpp

["janis at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #7 from janis at gcc dot gnu dot org  2006-07-05 20:35 -------
Regression tests using the reduced testcase from comment #3 on mainline for
powerpc-linux identified this patch where the test starts failing:

    http://gcc.gnu.org/viewcvs?view=rev&rev=103604

    r103604 | mmitchel | 2005-08-29 14:08:50 +0000 (Mon, 29 Aug 2005)

and this one where it starts passing again:

    http://gcc.gnu.org/viewcvs?view=rev&rev=110693

    r110693 | mmitchel | 2006-02-07 11:11:30 +0000 (Tue, 07 Feb 2006)

The regression hunts didn't use any special options and didn't ICE, but got
these messages:

elm3b11% /opt/gcc-nightly/trunk-20060131/bin/g++ -c 28088.cc
